It could be for lots of reasons, but it’s highly likely Loren is right. Pretty much all big companies do this to whatever smaller companies they can get away with doing it to. The longer they avoid paying out money the less interest, fees, etc they pay and the more money they have to earn money with. So find your leverage points and use them. Small claims/mechanics liens are powerful but keep them in your back pocket. You could talk to other contractors that have worked with them to see if they do it to everyone and if they eventually pay. If so, leverage harder.
